| 摘 要： | 稳定是高墩大跨刚构桥设计和施工过程中必须关注的关键性问题，而非线性稳定能真实地反应由初始缺陷引起的几何变形和结构中的局部材料已经进入非线性等对结构极限承载力的影响，故尤为重要。以主跨200m的贵州桐梓河特大桥为背景，考虑结构的几何非线性和材料非线性，对该桥最大双悬臂施工阶段的非线性稳定进行了模拟计算分析。

| Abstract: | Stability of rigid frame bridge with high pier and long span is one of the key issues to which attention must be paid in the design and construction.The nonlinear stability can truly reaction from the initial geometric distortion caused by a defect of local materials and structures has entered for the ultimate bearing capacity of nonlinear structure,so it is particularly important.Based on tongzi river bridge with a main span 200m,considering the geometrical nonlinearity and the structure of material nonlin... |
